A suite of partly inter-connected lakes and swamps of varied size, salinity, permanence and substrate (peat and inorganic), in an internally draining catchment. The open lakes are used for moulting by thousands of Australian shelduck (Tadorna tadornoides) and for drought refuge by tens of thousands of other ducks, while the sedge- and shrub-dominated swamps support an important population of Australasian bittern (Botaurus poiciloptilus) and three types of nationally vulnerable orchid. Vegetation communities of the Site’s wet flats are among the few remaining in non-coastal parts of south-western Australia and the Site has some of the largest natural sedgelands in Western Australia. It is used for nature conservation, but agriculture occurs in adjoining lands, notably grazing of domestic sheep and cattle and tree plantations. Illegally released feral pigs cause considerable damage to vegetation and soil.
